They killed most linkshells, most dynamis groups and now bring this kind of stuff at a point when, lets be honest very few players can be bothered to re-establish themselves into shells to get points and deal with drama again.
The nature of the content they designed here is actually very nasty, it's not a matter of join a ls, get 5 items and done. It's a matter of "grats on finishing your relic to 99, now you are indebted to do the other 17+ peoples multiple relics/emps/mythics to finish theirs too" and you're a **** if you don't come to every run afterwards (hence items needed

). Ingenious really, turns an annoying trial into a really long timesink which locks you in for no reward, so this trial isn't actually "get 5 marrows", it's "kill ADL/rex/ or whatever till you finish every other persons weapon in the group" doesnt sound so easy now does it? I've done old XI content and I know how it works and the tricks the devs use to lock you in for the long haul.
